Hello I have 4 Madagascar Rainbow fish and I know I have 2 males but I cant tell if my other 2 are females. How do I know if the other two are female?

    The standard answer is 'Males are far more colourful than females and have a pointed dorsal fin as opposed to the more rounded dorsal of the female.' Usually colors become more obvious as cichlids mature, and because you know you have two males, you should be able to visually compare them to the two unkowns and make a fairly good judgement. Of course, if they pair up and produce eggs, then you have a definite answer:) Good luck.

I bought one about a year ago and he was the only one in the tank with about 20 danio's and he has grown quite a bit. He's about as big as they can get and he is in a 29 gallon, but I have a 10 gallon with mollies and they actually had fry and so I went to petsmart to buy them a mesh breeder. I looked to see if they got more madagascars in stock and they had about 10 for a limited time and so I got two females. My male didn't seem too happy with them at first but they are about a 1/3 his size are they too small to breed with him? Because I don't want to try it and they get hurt I just wanted him to have some friends and I do want to breed them because I have grown to love my male. I have been searching for more for so long I just don't wanna risk it if the two females will get hurt.

    I can definitely understand your wanting to keep them all safe. It sounds like you may want to keep the femailes separate, in the 10 gallon, to keep them safe until they get big enough to breed. If and when you do try to introduce them with the male, just be ready to separate them if they don't seem to adjust. Also, sometimes you can put a tank divider in to give them a chance to get familiar with, but out of reach of each other. I'm excited about your new fish!

     I would ask a local fish store to special order it for me.  In your large area, there should be lots of fish stores you can check with. You can also try online.

These fish are great! My local fish store had one lonesome Madagascar Rainbow, so I bought him and he is a delight. Begs at the front of the tank, very active, very agile almost acrobatic..and most of all, very peaceful. He lives in a 95 gal with 7 Boesmani Rainbows, tetras, gouramis, loaches etc. I have been looking for more, but with no luck, They seem to be pretty rare.

I have had my Madagascan Rainbowfish for a while now and although they are pretty rare, are very good for a beginner with a tank of 30 gallons.

    As long as you keep pristine water they are very easy. They aare however very sensitive to change.

Are they easy to breed?

    The Rainbow fish is no where near as easy to bred as a molly or guppy. These fish spawn in very fast moving water and would need the current duplicated inorder to properly breed. If you set up the right environment you should be able to breed these fish. The difficulty is getting the tank right and the rest does its own thing.

I found a male and female at a local pet store and have had them in my 55g for a year. The male was 3 inches and showed great color even tho there wasn't other males in the tank. I would always see them schooling up with my roseline barbs. Unfortunately, I came home today and my male had died. I keep up with my tank with general maintence and haven't lost a fish out of the blue in the 2 years I've had the tank up. Has anyone else had this happen with the madagascar rainbows and what can cause it? Other fish seem to be fine. I did add 3 leopard corys a few days ago, but they are harmless. Thoughts?

    The Leopard Corydoras certainly did not cause the death of your Rainbowfish. At times, fish simply die, and there are no plausible explanations for why. Perhaps buy another one?
